Using psychology to design your product – Hacker Noon
If you provide content that your users don’t need, you create clutter on your design that detracts from the user experience. Hick’s law says that the more options you bring before users the longer the decision making process.
Most psychologists agree that human beings seek the easiest and quickest way to get things done. That translates that to a clutter-free website and a user-friendly interface. If you expose your web visitors to a choice of too many pictures or products, they will take longer to look at them and to make a choice.
They might get confused and fail to buy. Alternatively, they might buy and but later feel dissatisfied out of the belief that maybe other products were better than what they chose. The exasperation or satisfaction gained from viewing numerous items depends on the cognitive load presented to the user.
The cognitive load is the cumulative amount of mental effort or thought used by a person to complete a task. Even with this multiplicity of objects, Hick’s Law and the Von Restorff effect take precedence.
According to the Von Restorff effect, when faced with many similar objects, the unique one in the group remains in memory long after the experience. Following that principle, you should endeavor to make important aspects such as call-to-action buttons look different from other aspects of your application or site.

Functional Fixedness Stops You From Having Innovative Ideas
To see alternative, innovative solutions more easily, reframe the design problem. Abstracting the problem by removing the surface details minimizes the opportunities for functional fixedness and allows you to focus on the core issue. Once the problem is abstracted, it is easier to recognize related fields of expertise from which to draw inspiration. Research has found that when people look for inspiration from distant domains, they generate more creative solutions than when they consider only domains closely related to the original, non-abstracted representation of the problem.
For example, in a study run at Carnegie Mellon University, participants were asked to design a power strip in which large plugs wouldn’t block adjacent outlets. Researchers also created an abstracted version of this problem: How to fit objects of different sizes into a container so that they don’t block each other and take full advantage of the container’s capacity? In this reframed problem, the surface features of power strips, plugs, and outlets were stripped away to avoid functional fixedness. When given the abstracted problem, participants in the study were able to identify remotely related, yet potentially relevant domains of expertise such as contortionism, landscaping, carpentry, and Japanese aesthetics. People who collected inspiration from these distant-yet-structurally-relevant domains produced the most novel, practical solutions to the original design problem, proving that creativity increases when functional fixedness is prevented.
Similarly, whenever you are faced with a design problem, resist the urge to immediately jump into brainstorming solutions. Instead, abstract the problem and identify potentially related sources of inspiration. (Tip: After you’ve abstracted the problem, take a break so you can allow yourself to “forget” the original formulation.) Then, consider how the problem is solved in these outside fields, and how those solutions could be translated back into your design.
